Thunderbolt 3 provides up to 40Gbps speed, doubling the speed of the previous generation while remaining bi-directional and full duplex — USB 3.1 at 10Gbps, and DisplayPort 1.2 - meaning that one computer port will be able to connect to Thunderbolt devices, every display, and billions of USB devices.
It is four times faster than the USB 3.1, backward compatible with existing USBs, and is the quickest Bi-directional cable so far.
It is driven by Intel's new Alpine Ridge controller, which now features an integrated USB 3.1 host controller. The increase in max bandwidth means that Thunderbolt 3 will support up to two 4K @ 60Hz displays or a single 5K @ 60Hz display off a single cable.
• Twice the video bandwidth of any other cable
• Single-cable connection for two 4K 60Hz or a 5K 60Hz display
• 2 streams (eight lanes) of DisplayPort* 1.2 or HDMI 1.4
• Optional notebook charging up to 100W while simutaneously supporting data and display transfer.
• Standard 15W to bus-powered devices
• Bi-directional, multi-protocol (Thunderbolt, DisplayPort and USB)
-4 lanes of PCI Express Gen 3
-8 lanes of DisplayPort 1.2 - Supports two 4K displays (4096 x 2160 30bpp @ 60 Hz)
-USB 3.1 (10 Gbps) – compatible with existing USB devices and cables
• DisplayPort 1.2:
- Connect DVI, HDMI, and VGA displays via adapters
